What is the difference between 93 and 92 gasoline

The anti-knock properties are different, and the proportion of the substance content is different.

"No. refers to the gasoline octane number index, such as 90, 93, 97, 98, etc., simply put, the higher the value, the higher the anti-explosion ability, to put it bluntly, the higher the value, the more stable the combustion in the engine, the small riot, the good for the engine.

Professionally, it can be blended in different volume ratios to make standard fuels with octane numbers from 0 to 100. The higher the volume percentage of isooctane in the mixture, the better its anti-knock performance.

When measuring the octane number of the sample in the octane number testing machine, the compression ratio is increased until the standard deflagration intensity appears, and then, the compression ratio is kept unchanged, and the standard fuel of a certain composition is selected to be measured under the same test conditions, so that the engine produces a deflagration of the same intensity. When it is determined that the standard fuel taken happens to be composed of 70% isooctane and 30% n-heptane, the octane number of this test oil can be assessed to be equal to 70. Obviously, 92 petrol is slightly worse than 93.

These numbers represent the octane number of gasoline, that is, the anti-knock resistance of gasoline, 92 and 93 gasoline are gasoline with an octane number of 92 and 93, suitable for mid-range cars (lower compression ratio), high-end cars generally choose gasoline with higher grades. In terms of practical use, there is little difference between No. 92 gasoline and No. 93 gasoline. No. 92 gasoline is the fifth stage of the national standard gasoline.

The most significant changes are the reduction of the sulphur limit from 50 mg/kg to 10 mg/kg and the manganese limit from grams per litre to grams per litre. At the same time, the octane number and anti-knock of gasoline have been reduced, and its anti-knock index has been revised to "not less than". In actual use, there is no difference between No. 92 gasoline and No. 93 gasoline.

This is the reason why some cars have 92 gasoline and 93 gasoline in the specifications of the car. Of course, if it is a luxury car or not bad for money, it is better to choose a higher grade of gasoline.

There is no difference, it's the same If it helps, please set it up, thank you.

Hello, there is no difference. Have a great trip. If I can help you, please set it to, thank you!

No. 93 gasoline corresponds to No. 92.

Since the introduction of the unified national V standard, No. 93 gasoline corresponds to No. 92, and No. 97 corresponds to No. 95. The higher the oil number, the better the knock resistance. Because the emission standards are more stringent, the upgraded oil number can not only reduce pollutant emissions, but also extend the service life of the car and reduce the maintenance and repair costs of the vehicle.

In turn, it reduces corrosion on the engine of the vehicle and deposits in the air intake system, protects the engine and exhaust system, and has a more protective effect on the vehicle.

Car oil number in ** look?

Car fuel consumption can be viewed on the fuel tank cover of the vehicle, when the motor vehicle is in use, it needs to be used in strict accordance with the specified oil number, otherwise it will affect the engine work, resulting in insufficient engine power, louder noise, and aggravated vibration, which will lead to an increase in vehicle fuel consumption, so the car must be added and used in accordance with the specified fuel consumption when refueling.

Precautions for gasoline use

1. Adjust the engine appropriately according to the label of the gasoline used. When a gasoline engine uses gasoline with an octane rating lower than the specified marking, the ignition and fuel supply systems should be adjusted.

If you can hear a continuous knocking sound when using the recommended gasoline on flat ground or at a steady speed, you should check the status of the engine tuning, the quality of the gasoline, and the compression ratio of the engine. If you hear some slight knocking sound in a short period of time during acceleration or climbing, it is normal and do not worry.

2. Adjust according to the altitude. According to the altitude of the area where the car is driving, the ignition advance angle and the oil level height and idle speed measuring hole of the carburetor float chamber should be adjusted in time. After the car travels from the plain (or plateau) to the plateau (or plain), the ignition angle should be appropriately advanced (or postponed) in time.

3. Prevention of air resistance. When the car is driving in hot summer or plateau and alpine areas, heat insulation materials should be used to separate the gasoline pump from the oil pipeline, minimize the bends of the oil pipeline, and strengthen the ventilation of the engine room to prevent air resistance. If gas blockage has occurred, cold water can be poured on the gasoline pump, fuel pipe, and intake pipe of the gasoline engine or the engine can be stopped to cool down naturally.

4. Remove the carbon deposits in the engine. When repairing the engine, the maintenance personnel should thoroughly remove the carbon deposits in the intake pipe, intake and exhaust valves, and combustion chamber, so that the surface is smooth and there is no residual glue or dirt, so as to prevent the "knocking" or "pre-ignition" phenomenon caused by glue.

5. Prevent the gum of gasoline. Car fuel tanks should be filled with gasoline frequently to minimize the amount of air in the tank to reduce gum formation.

Summary. Hello, glad to be able to answer your questions! The numbers 92 and 93 represent the octane number of gasoline, that is, the anti-knock resistance of gasoline, which is suitable for mid-range cars, that is, the compression ratio is relatively low, and high-end cars generally choose gasoline with a higher grade

1. Gasoline octane number is different, 92 octane number 92 and 93 gasoline are gasoline with octane number 93;

Gasoline is the fifth stage of the national standard gasoline. No. 93 is the old grade of gasoline;

The most significant change between gasoline and gasoline 93 is that the sulphur limit has been lowered from 50 mg/kg to 10 mg/kg and the manganese limit has been lowered from grams per litre to grams per litre.

What is the difference between 93 gasoline and 92 gasoline.

Hello, glad to be able to answer your questions! The numbers 92 and 93 represent the octane number of gasoline, that is, the anti-knock resistance of gasoline, which is suitable for mid-range cars, that is, the compression ratio is relatively low, and high-end cars generally choose gasoline with a higher number: 1. The octane number of gasoline is different, and the 92nd octane number of 92 and 93 gasoline is the gasoline of the octane number 93 The gasoline is the fifth stage of the national standard gasoline.

No. 93 is the old grade of gasoline The main change between No. 93 gasoline and No. 93 gasoline is that the limit of sulphur content index is reduced from 50 milligrams per kilogram to 10 milligrams per kilogram, and the limit of manganese content index is reduced from grams per liter to grams per liter.

I hope mine can help you and have a great life!

If you add 93 to the original car, can you add 92.

Hello, this is okay, 93 is 92 seems to improve the process to reduce the emission of pollutants, but also to reduce the label.

The difference is as follows: There is a slight difference in the composition of gasoline and gasoline 93.

The anti-knock performance of No. 92 gasoline is lower than that of No. 93, but other indicators in gasoline such as sulfur, benzene, aromatics, manganese, etc. are lower and more environmentally friendly.

No. 92 gasoline is the national fourth-stage standard gasoline, and No. 92 gasoline is the national fifth-stage standard gasoline.

The limit of sulphur content in gasoline was reduced from 50 milligrams per kilogram to 10 milligrams per kilogram, and the limit of manganese content was reduced from grams per liter to grams per liter.

Compared with No. 93 gasoline, the octane number and anti-knock resistance of gasoline have been reduced, and its anti-knock index has been revised to "not less than".

6. In fact, in actual use, there is no difference between No. 92 gasoline and No. 93 gasoline, which is why No. 92 and No. 93 gasoline are indicated in the parameters of the car.

The anti-knock performance of No. 92 gasoline and No. 93 gasoline is different, No. 92 is lower than No. 93, but other indicators in gasoline such as sulfur, benzene, aromatics, manganese, etc.

No. 93 gasoline is the fourth stage of the national standard gasoline, and No. 92 gasoline is the fifth stage of the national standard gasoline.

The limit of sulfur content in No. 92 gasoline was reduced from 50 milligrams per kilogram to 10 milligrams per kilogram, and the limit of manganese content was reduced from grams per liter to grams per liter.

Compared with No. 93 gasoline, the octane number and anti-knock value of gasoline have been reduced, and its anti-knock index has been modified to "not less than".

The level of gasoline marking only indicates the size of the octane number of gasoline, and different grades of gasoline should be selected according to the different compression ratio of the engine. Mid-range cars with compression ratios between should generally use 93 gasoline; Cars with a compression ratio greater than 97 should use 97 gasoline. The compression ratio of domestic cars is generally above 9, and it is best to use 93 or 97 gasoline.

The main basis for the selection of gasoline is the compression ratio of the engine, and the compression ratio and other parameters have been set in the engine computer, so the owner must choose gasoline in strict accordance with the requirements of the instructions, if the compression ratio of the engine is set low, and blindly use the high-grade gasoline, it will produce the phenomenon of acceleration weakness in driving, and at the same time cause the situation of burning oil.
